INTERIOR LAMP BATTERY SAVER CONTROL

If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the battery 30 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when
• a signal is received from an Intelligent Key or main power window and door lock/unlock switch, or when the

front door LH lock assembly (key cylinder switch) is locked or unlocked

• a door is opened or closed
• the Intelligent Key is removed from or inserted into the key slot.
The Interior lamp battery saver control time period can be changed with the function setting of CONSULT-III.

ILLUMINATION CONTROL SYSTEM

System Diagram

INFOID:0000000001712566

System Description

INFOID:0000000001712567

The illumination lamps operation is dependent upon the position of the lighting switch (combination switch).
When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) the BCM
(body control module) receives input requesting the parking lamps to illuminate. This input is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs
power to the parking and illumination lamps, which then illuminate.

BATTERY SAVER CONTROL

When the lighting switch (combination switch) is in the 1ST or 2ND position and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the illumination
lamps remain illuminated for 30 minutes unless the lighting switch position is changed. If the lighting switch
position is changed, then the illumination lamps are turned off after a 30 second delay. When the lighting
switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps
have been turned off by the battery saver control, the illumination lamps illuminate again.

Part name

Description

BCM

The BCM monitors the lighting switch position with the combina-
tion switch reading function. The BCM requests, via CAN com-
munication, that the IPDM E/R activate the tail lamp relay.

IPDM E/R

The IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication network.

Combination meter (illumination control switch)

The illumination control switch is a part of the combination meter.
The combination meter controls illumination intensity by varying
ground to the illumination lamps based on the illumination control
switch position.

Combination switch

The combination switch provides input to the BCM about the light-
ing switch position.
